Overall Weight: Approx. 260g (excluding battery)

Ingress Protection Rating: IP53

Multiple Power Supply Modes: Powered by common batteries; 2 pieces of AA batteries for easy replacement.

Ultra‑long Working Time: Continuous normal working time of approx. 200 hours and standby time of 30 days, energy‑saving and eco‑friendly. Supports charging and low‑battery reminder.

Advanced Programming Function: Operators can judge the metal content of detected objects via sound‑light prompts.

Power‑saving Function: Automatic wake‑up and automatic power‑off.

Operation & Control Device: One‑key power on/off; Sensitivity adjustable from level 0 to 30 (low to ultra‑high), with quick switching between sensitivity levels.

Compatible with earphones or adjustable alarm modes to meet different environmental requirements.

Multiple Detection Modes: Ferrous metal, non‑ferrous metal and all‑metal detection modes.

Users can select a mode for detection according to actual conditions, with no parameter setting required.

Sensitivity Range: Covers one detection grade.

Detection Capability: ≥300mm

Continuous Working Stability: ≥200h

Alarm Volume: ≥80dB(A). The alarm tone shall be distinguished from other prompt sounds; the volume increases with the size of detected objects.

Alarm State Reset: The detector features automatic alarm reset. The alarm stops immediately when it is away from the detected object by the specified distance.

Ultra‑low Operating Environment: Continuous operation for 4 hours at -40~+70±2℃.

Anti‑interference Performance: Multiple detectors can work normally simultaneously with a spacing of 0.2m between each other.

Resistance to Surrounding Metal Interference: Moving metal objects beyond 0.2m shall not trigger false alarms. For detectors close to large metal objects, their detection performance shall automatically recover within 1 minute after moving away from such objects.

Adaptive Performance: Applicable to complex surrounding environments.

Material: Shock‑resistant and impact‑resistant PC+ABS plastic.

Radiated Magnetic Induction Intensity: The magnetic induction intensity of the radiated magnetic field emitted by the detector shall not exceed 10μT at any point on its surface.

Detection Sensitivity: Tested with test objects and corresponding detection distances specified in Table 1 of GB 12899‑2018, with no missing alarms.

Test Object T1: 5.5cm; Test Object T2: 6.0cm; Test Object T3: 9.5cm; Compliant with Grade A standard.

Charging Port: Standard Type‑C port for device charging.
